Test Services

We mainly offer Highly Accelerated Life Testing (HALT) and Highly Accelerated Stress Screening (HASS) for test services. Our HALT & HASS testing lab provides services to help shorten new product development time, decrease warranty costs and significantly improve product reliability. This is accomplished through stepped temperature & vibration tests to establish product limits and then with rapid thermal cycling and vibration. We work collaboratively with our customers to provide assistance for their HALT and HASS test project. Through careful implementation of each test protocol and industry-leading reporting, our team provides the data necessary to accurately identify design weaknesses or other points of failure.

Highly Accelerated Life Testing (HALT) – an effective tool using cold temperature, hot temperature, thermal transitions, and random vibration to expose latent defects and weak links during a product’s design phase. By eliminating failure mechanisms found during the HALT process, product reliability is improved in a short period of time. Using high levels of stress, in just a few days HALT exposes the same failure modes that are likely to occur under normal stress conditions over an extended period of time.

Highly Accelerated Stress Screening (HASS) / Environmental Stress Screening (ESS) – a screening process utilizing rapid thermal transitions and random vibration to expose process variations in manufacturing. HASS is used to monitor outgoing quality and improve product reliability.

For other test service inquires, please contact the Director of CQRME.

Data Analysis Services

To complement our test services, we also offer data analysis services. Our data analysis services mainly focus on delivering Reliability Data Analysis, which includes:

  • Life data analysis (also referred to as "Weibull analysis")
  • Accelerated testing data analysis
  • Degradation data analysis

For other data analysis inquiries, please contact the Director of CQRME.
